Power failure protection device, control system and power failure protection method of the control system

Abstract

The present invention discloses a power failure protection device, a control system of the power failure protection device and a power failure protection method of the control system. The device comprises a protection branch, and the protection branch is sequentially arranged with a charging module, an energy storage module and at least two-stage boosting module; wherein the protection branch protects the control system from power failure when the control system is powered down; the charging module is configured to charge the energy storage module by using a power supply when the control system is not powered down; the energy storage module is configured to store energy obtained by charging the energy storage module; and the at least two-stage boosting module is configured to boost a current voltage of output energy of the energy storage module to a target voltage of the control system in at least two stages, and the at least two-stage boosting module comprises a first-stage boosting module and a second-stage boosting module, wherein the first-stage boosting module and the second-stage boosting module have different structures. The device can solve the problem that automatic equipment lacks power failure protection, and achieves effect of realizing the power failure protection of the automation equipment.

Description

technical field [0001] The invention belongs to the technical field of electronic circuits, and in particular relates to a power-down protection device, a control system and a power-down protection method thereof, in particular to a power-down delay circuit protection device, a control system having the device, and the control system power-down delay protection method. Background technique [0002] With the continuous improvement of factory automation, automation equipment gradually replaces the original high-intensity repetitive manual work. In automation equipment, control equipment is the center of automation equipment, and a stable operating system is the basis of control equipment. Operating systems such as CNC machine tool operating systems, industrial robot human-computer interaction systems and other system control units play an important role in the control of automated production; however, if a sudden power failure occurs during work, the system files will be dama...
